ODI Training in Chennai

ODI Training in Chennai

Learn an advanced ETL cum ELT tool from experts in real-time to work on a live project or to leverage better opportunity in IT industry. Oracle Data Integrator provides a new declarative design(Interactive UI) approach to defining data transformation, integration and validation processes, resulting in faster(can handle huge data), simpler(Easy debugging) and cheaper(due to ELT, which is an exclusive part of ODI) development and maintenance of data warehousing.

About Course

This course enables you to work in a real project implementing ODI (11g or 12c ) and how to build a data warehouse using different modules of ODI, how to transform and validate data from one form to another (files, XML, database etc). We customized this course curriculum to meet the current industry standards. We guarantee that even a Non-ETL participant having very little knowledge of database can learn ODI.

Course objectives                             

At end of this ODI training by Htop, you will be able to,

  • Learn ODI architecture and how its different from other ETL tools
  • Build master and Work Repositories.
  • Create Agent(ODI’s execution engine) and how to configure the agent to meet optimization.
  • Create different objects like Packages, Interface (Mapping), procedure, Models and variables to design a data transformation workflow.
  • Learn how to handle Exceptions in workflow through the customizable code and through rich ODI components like Load plans.
  • Customize view of ODI repositories for every user through its Security architecture.
  • How to implement physical and logical architecture and migrate the logical code from development to production environment.
  • Implementation of KMs for different technology and how to customize your own KM to meet the complex requirement.
  • Reverse Engineer metadata in ODI for different technology like RDBMS, Files, XML, excel etc.
  • Code optimization techniques to speed up the overall batch process and learns how ODI excels it.
  • Using customize java APIs in different objects of ODI to make code environment independent.
  • Implementation of CDC and SCD in ODI.
  • Learn new features provided in latest 12c version and how it integrates more advanced technology like Big data.

Who can learn this course?

ODI can be learned by anyone who wants to make his carrier in Data science as Data analyst.This training will be suitable for

  • Fresh Graduates
  • College / School Students
  • Job Seekers
  • Data Scientist works in ETL and reporting tool
  • Who are having good knowledge in Java

Job Opportunity

Many companies are now moving from other ETLs like Informatica, Datastage, Abnitio to ODI because of its capability of handling huge data in a faster and cost-effective manner. After this training, you will surely be able to handle interviews questions and can work on any live project implementing ODI.
